In my asp.net MVC 3 application am using Jqgrid as my grid. It contains a checkbox and i managed the event as below
$("#list").find('input[type=checkbox]').live('change', function () {
if ($(this).is(':checked')) {
var _row = $(this).parent().parent();
}
});
i got the row using $(this).parent().parent() i want to get the id of the _row . How can i get the id? Is there any method please share
This should do the trick:
$('#list').find('input[type=checkbox]').live('change', function () {
if ($(this).is(':checked')) {
var row = $(this).parent().parent();
var rowId = row.attr('id');
}
});
If you are using default value of idPrefix option of jqGrid (which is empty string) otherwise the id will prepend with value of this option.
On select row you can get the id of selected row. In fact when you check a checkbox you also select a row so:
onSelectRow: function(id){
yourId = $("#yourGrid").jqGrid('getGridParam', 'selrow');
alert("The id of checked row is: "+yourId);
}

I am using Kendo UI grid without pagination. I have set the below code to load the data in the grid view while scrolling
scrollable: { virtual: true },
My problem is, I have selected 100th row in the grid by scrolling . I am refreshing the grid. After refresh, I need to select the 100th row again. Is it possible ?
Regards
Senthil
After refresh select the row you need as shown below
var grid = $("#grid").data("kendoGrid");
grid.select("tr:eq(100)");

Basically the question is annotate the row that you have selected when it changes to do so and then in dataBound event select that same row.
In order to save the selected row you can do:
change: function (e) {
// Save some information from the selected row
var item = this.dataItem(this.select());
// Here we save uid
var uid = item.uid;
this.selectedRow = uid;
},
dataBound: function (e) {
// If we have any row selected
if (this.selectedRow) {
// Use this.select for selecting it
this.select("tr[data-uid='" + this.selectedRow + "']");
}
}

I am using a custom formatter to create hyperlinks in one of the columns of my grid.
In my code, there are cases when I need to disable the selected row. The row disabling works as I want it to, but the hyperlink for that row is not disabled. I can not select the row and all the other column values are displayed as grey colored to indicate that the row is disabled. The only column whose content does not change color is the one having links.
Any ideas on how to disable links?
This is my loadComplete function:
loadComplete: function (data) {
var ids =jQuery("#list").jqGrid('getDataIDs');
for(var i=0;i < ids.length;i++){
var rowId = ids[i];
var mod = jQuery("#list").jqGrid('getCell',ids[i],'mod');
if(mod=='y'){
jQuery("#jqg_list_"+rowId).attr("disabled", true);
$("#list").jqGrid('setRowData',ids[i],false, {weightfont:'bold',color:'silver'});
var iCol = getColumnIndexByName.call(this, 'adate');
$(this).jqGrid('doInEachRow', function (row, rowId, localRowData) {
$(row.cells[iCol]).children("a").click(function (e) {
e.preventDefault();
// any your code here
alert("No Good");
return false;
});
});
}
}
}
I want the links disabled in all the rows where the value of the column mod=y
You can try to use onClick callback of dynamicLink formatter described here, here and here. It gives you maximum flexibility. Inside of onClick callback you can test something like $(e.target).closest("tr.jqgrow").hasClass("not-editable-row") and just do nothing in the case.
i have table with 4 rows and when i click on any row then a new is getting added just after row where i clicked. here i am giving my code just to show how i achieve it with jquery.
my jquery by which i adding a new row just after the row where i clicked.
$(document).ready(function () {
$("table#Table1 tr").click(function () {
var $tr = $(this).closest('tr');
var myRow = ($tr.index() + (++counter));
$(this).after("<tr ><td>" + myRow + ") </td><td><img src='Images/closelabel.png' id='imgExpandCollapse' alt='ABC' style='cursor:pointer'/></td><td>Name : New one</td><td>Desig : CEO</td></tr>");
});
});
the problem is that i am adding new row with jquery but click event is not getting attach with new. so please guide me for the best approach to attach click event with new row.
You want to use .live(..) to bind the event. This will allow dynamically generated DOM elements to use the same event.
$("table#Table1 tr").live( 'click', function () {
var $tr = $(this).closest('tr');
var myRow = ($tr.index() + (++counter));
$(this).after("<tr ><td>" + myRow + ") </td><td><img src='Images/closelabel.png' id='imgExpandCollapse' alt='ABC' style='cursor:pointer'/></td><td>Name : New one</td><td>Desig : CEO</td></tr>");
});
Try $.fn.delegate
http://api.jquery.com/delegate/
Try changing -
$("table#Table1 tr").click(function () {
to
$('table#Table1 tr').live('click', function() {
That should ensure jQuery binds the click event to all table rows, including those that are created dynamically.

while selecting the checkbox in the jqgrid i need to sum the values of row data in jqgrid and i need to display those data in the footer of the jqgrid.Please help me out how to achieve that.
Thanks in Advance,
Silambarasan,
You can use footerData method. See here and here for details and demo examples.
I got the answer ,i solved that issue.
The Answer is.
footerrow:true,
userDataOnFooter:true,
onSelectRow: function(rowId)
{ handleSelectedRow(rowId); },
function handleSelectedRow(id) {
var jqgcell = jQuery('#list1').getCell(id, 'headerId');
var amount = jQuery('#list1').getCell(id, 'amount');
var cbIsChecked = (jQuery("#jqg_list1_"+jqgcell).attr('checked'));
if(cbIsChecked==true)
{
if(amount!=null)
{
totalAmt = parseInt(totalAmt) + parseInt(amount);
}
}else
{
if(amount!=null)
{
totalAmt = parseInt(totalAmt) - parseInt(amount);
}
}
myGrid.jqGrid('footerData','set',{needbydate:'Total Amount:',amount:totalAmt});
}
The above function is used to get the values of the selected row by clicking the checkbox you will get the value from that by calling the external function like "handleSelectedRow" you pass your row object from that you do your operation and finally update your answer by using the jqGrid function like "myGrid.jqGrid('footerData','set',{needbydate:'Total Amount:',amount:totalAmt}); "
It will update in your footer.
I'm using setCell to set the value of a cell. The problem is it is still calling the customFormatter specified for the column. Is there anyway I can set the value of this cell without it having to go through the customFormatter?
First of all the custom formatter will be used on every grid refresh, so to set the cell value you have to do this after the custom formatter. The best place to do this is inside of loadComplete or gridComplete event handler.
To set the cell value you can use jQuery.text for example. So you should get jQuery object which represent the cell (<td> element) and then use jQuery.text or jQuery.html to change the cell contain. How I understand you, you knows the rowid of the cell and the column name which you want to change. The following code could be:
loadComplete: function() {
var rowid = '2', colName = 'ship_via', tr,
cm = this.p.colModel, iCol = 0, cCol = cm.length;
for (; iCol<cCol; iCol++) {
if (cm[iCol].name === colName) {
// the column found
tr = this.rows.namedItem(rowid);
if (tr) {
// if the row with the rowid there are on the page
$(tr.cells[iCol]).text('Bla Bla');
}
break;
}
}
}
See the corresponding demo here.
